RFR: JDK-8260404: jvm_io.h include missing in a number of files

[Thomas Stuefe]

One of the last include corrections caused a build error on our AIX machines because compile.cpp uses jio_snprintf() without including jvm_io.h.

I did not deeply follow up on the why, but "8260307: Do not include method.hpp in frame.hpp" is a possible candidate. AIX builds without JFR and hence miss a number of include chains other platforms have.

I scanned hotspot sources for files using jio_snprintf but not including jvm_io.h. There are some hits, which should be fixed.

All this is trivial, right?
